MACHINE non CLOSING CHANNEL LIPS or SHOES.

GlosingChannel Lips ot Shoes, of which the;

following is a Specification;

"Ih's ,invention relates to; processes .andvv McKay machines used in malringshoes.

In making what is known r`as a shee,.a channel is cut in thesole the lip of which is turned back, ardyin this` channel thread is buried in stitching'the sole to the upper. Cement is then placed `inthe channel,` the sole is-lnoistened with water,r and as now done, thelip is turned down into the channel by a hand toolaterwhieh the shoe f y p n A; the stand having abase l which maybe is passedl through whatgis known as a beating-out vor leveling machine bydwhich the soleisy linishedand the lipsmoothed out in theichann'el where. it is held by the cement. f- After 'thestitching and g before turning down the lip by hand, `it. is necessary that the shoe'- should beplacedon a last or form which isheld in anysuitable ysupltiort so that the operator can grasp'a tool with'both'hands to Work on the lip. The shoe is generally placed onv the 1 form or metal, lastr of the leveling 'machine and there' worked on. `When'this is done, there is danger V"of injury to the Operators hands. 1 f

.f The tool -generally used is ahal-roundiile held between the hands and worked so that". the edge willV come in contact with thelip.

; By my/process, I use a revolving member, preferably of cylindrical form and roughened on the outside so that it will catch the leather, against which `a shoe is pressed by hand; yVVit-h-,my process, "instead of having the shoe'held-rigidly and operating on it by hand; I hold the shoe in the hands and bring it 'with a smoothing motion against a revolving tool which, preferably,isalso so .held

that /it yields to pressure'. e The ,shoe is carried against this tool with a 4circular motion and the tool revolves.
